Black Mountain Trail is a hard hike in Maine's Deboullie unit, managed by State Park and Recreation. It is a long, steep out-and-back route that climbs from about 1,168 feet to nearly 1,971 feet, with a total round-trip elevation gain of about 2,623 feet and a one-way gain of about 1,226 feet. The trail is roughly 8.6 miles long, and the steepest stretch comes at about 3.5 miles in, with a grade of about 44%. Summer is the most comfortable time to go. Typical averages from a nearby weather station in Allagash show July highs around 77°F with lows near 52°F, while that station sits well below the trail, so temperatures on the summit run cooler. The Deboullie Loop Trail starts just 0.1 mile away, and Whitman Ridge is about 0.4 mile off. Island Pond Trail and Whitman Valley are both within about a mile and a half.
